Power supply supervisory ICs
These multi-voltage supervisory ICs are designed with new circuits for monitoring negative-voltage and over- and under-voltage conditions.
The ADM2914 and the ADM12914 quad-channel voltage
supervisors, and ADM6339 microprocessor supervisor ICs enhance overall system
reliability by helping ensure voltage levels remain within specified levels.
The new circuits provide up to twice the accuracy of other devices designed to
monitor voltage supply rails in communications, industrial and instrumentation
The ADM12914 detects over-voltage and under-voltage (OV/UV)
conditions with 1.5 times the accuracy of competing supervisory circuits. The
supervisory IC prevents power supplies in medical ultrasound,
telecommunications equipment and other applications from slipping out of range.
This is especially important in today's power supply systems, which often
operate at below 1 V and where an over-voltage condition could cause
catastrophic system failure. The ADM2914/ADM12914 also includes an input-supply
shunt regulator that enables the device to be run off of higher-voltage
supplies, including 12-V operation in communications infrastructure equipment
and lithium-ion batteries used in hybrid vehicles.
The ADM6339 quad microprocessor voltage supervisory circuit
provides two times the accuracy of other devices in its class, and monitors up
to three positive and one negative voltage supplies. The ADM6339 incorporates
internally pre-trimmed under-voltage threshold options for monitoring 1.8 V,
2.5 V, 3 V, 3.3 V, 5 V and -5 V supply voltages. It is available with one to
three adjustable threshold options to extend design flexibility.
As part of a complete signal chain, the ADM12914 and ADM6339
supervisory circuits are compatible with ADI's point-of-load regulators,
including the ADP1740, ADP1741 and ADP2102, ADP2105, ADP2106, ADP2107, ADP2108,

Annual Salary Survey
Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.
There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.
But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
